Abstract
Abstract of the Disclosure:
A continuously wound strip of toweling, either solid wound or wound about a hollow central core, forms the roll with radial end surfaces. A pair of diametrically aligned, axial pin openings are formed in one of the roll end surfaces equally radially spaced from the central longitudinal axis with radially inner extremities radially outwardly of any roll core. If the roll is solid wound, a central axial opening is formed in the other roll end surface preferably semi-spherical in shape or if the roll is hollow core wound, the core forms the central axial opening at the other roll end surface. In either case, with dispenser pin support and central support at the opposite e roll ends, dispensing unwinding of the strip of toweling to the pin hole radially inner extremities releases the roll for endwise pivoting about the other roll end automatically dismounting the same. In addition to the central opening at the other roll end surface, a circumferential groove may be formed therein radially outwardly of the central opening to adapt the roll for versatile use with known dispenser dismounting structures.

This invention relates to an automatic dis-mounting roll for roll towel dispensers and more particularly, to such a roll specifically adapted for 5. use with a greatly simplified dispenser automatic roll dismounting structure. With the unique,automatiç
.
dismounting roll of the present invention, not only , , is the rol,l adapted for secure support during the , dispensing operations and likewise adapted,~or positive `~10. and eficient automatic dismounting-of the same, but ~ ' t~e roll also lends itself to greatly simplified manufacturing procedures so as to reduce production ' -costs over those required for prior automatic dis~
mounting roll constructions. As a'subsidiary ad~
15. vantage of the simplified automatic dismounting roll , of the present invention, other elements of structure -~ ' may be added thereto for supplying versatiIity in -use of, the roll in known prior automatic roll dis-mounting dispensers. -20. Various prior roll towel dispenser structures have heretofore been provided, some of which have '~
included automatic roll dismounting after a predicted amount of the toweling has been dispensed from the particular roll. In general, most of the prior dis~
25. pensers are hollow box-like in conflguration adapted ,~
for being wall mounted on a vertical wall surface and are usually selectively front opening for providing '' " ~ :

access to the interior of the dispenser c~binet in order to perform the toweling roll replacement operations.
Furthermare, since this class of dispensers make use of rolls o~ toweling, the toweling is dispensed in con-5. tinuous strip form downwardly from the dispenser during the operation thereof.
- More particularly, the roll of toweling is rotatably supported within the dlspenser with ~he maln longitudinal axis thereof between roll end holders.
10. The continuous strip of toweling is fed downwardly from the ro11 between a pair of rotatable dispensing rolls and from the dispensing rolls downwardly ad--- ~ jacent a cutting bar and from th~ dispenser. The roll of toweling is supported freely rotatable so ~ ; -15. that, upon selective rotation of the dispensing rolls ~ ~ ;

the used roll is completely exhausted of toweling.
25. Basically, the most common manner of pro-. ~ . ' . , :
~ 63 47~7 viding an automatic roll dismounting dispenser is to ~orm the roll end holders with a specific cooperable roll formation so that retention of the roll of towel-ing by the roll end holders at least at one end of the 5. roll is determined by the layers of toweling on the roll. In other words, the roll end holder and roll . are cooperably ~ormed such that the roll will be supported by the roll end holder properly rotatable . ..
or disperlsing until a given number of layers of the - `
10. -toweling have been rotatably wound therefrom, at ~.
which time, a portion of the roll end holder is auto- . -- :.
~ matically exposed to automatically remove the roll .
support of that particular roll end holder and the ~roll thereby is automatically released through .-- . 15. . gravity to pivot endwise about the other roll end holder ultimately falling downwardly to come to rest ~ ~`
within the dispenser used roll recess as hereinbefore : described. It is the rolls of toweling used by ~ ~
this general form of automatic roll dismounting dis- ~ .
20. pensers to which the improvements of the present : :
invention are directed.
Obiects and Summary of the Invention It is, therefore, an object~of this invention ~:
25. to provide an automatic dismounting roll for roll towel , ~, . .
~7~:~7 dispensers which is adap-ted for highly secure rotatable suppor-t in a dispe~ser during the normal dispensing operations of a strip of toweling therefrom, yet is :~
also adapted for efficient and positive automatic S. dismounting after a predicted amount of the strip of toweling has been thusly dispensed. According to the preferred embodiment principles.of the present :
invention, one of the roll end surfaces has diametrically ..
opposite pin holes formed axially therein equally 10. radially spaced from the main longitudinal axis of-the roll and radially outwardly o~ any roll core, . ~-and the other end surface of the roll merely re~uires .
structure adapted for central roll support. - For instance, if the toweling roll is of solid wound strip,~
lS. the central support for the other roll end surface - may merely be a central axial hole or opening and if . .
the roll includes a central core, the central support.
at *he other r~oll end surface may be in the core end . such as the opening of a hollow core. In any case, ~.
: 20. wi~h ~he roll dispenser supported by appropriate pins in the pin holes and a central support in the central support hole or opening, unwinding of the strip of toweling during dispensing to the pin hole rad}ally inner extremities will.release the one end of the -~
25. roll to pivot endwise about the other end central , " ' ' ' ' ' ' .
~L~47~17 ~ ~
support, there~y efficiently dismounting -the same.
It is another object of this invention to provide an automatic dismounting roll for roll towel dispensers o the foregoing general structure and 5. advantages which, due to the extreme simplicity of the roll support and dismounting concept, may ~e manufactured and supplied for a minimum of additional cost over rolls of toweling not including the auto-matic dismounting feature and at a manufacturing lO. cost less than prior automatic dismounting rolls of - toweling. . With a core wound roll of toweling, the only required added structure over the usual standard roll of toweling is the pin holes at the one roll en surface, and if the roll is solid wound without a ~
15. .core, only the central opening at the other roll end surface need be added to the pi~ openings. Thus, the cost of manufacture of the unique automatic dis~
mounting roll of the present invention over standard : ~ .
.
rolls of toweling is quite nominal despite the auto- :
,: ~
~: 20. matic dismounting advantages added thereto.
. It is still a further object of this in~ . ~
vention to provide an automatic dismounting roll for ~ ~ :
roll towel dispensers satisfying the foregoing objects, while still being perfectly adaptable to the inclusion ~5. in the structure of an additional element or elements ,:
, . . . .
:
7~7 supplying versatility for alternate use of the same roll of toweling with certain prior roll towel dispensers having a different form,of automatic dismounting roll.
Using the exact above discussed toweling roll structure 5. to supply a roll incorporating the unique features of the present invention, a circumferential groove may be formed in the other roll end surface spaced radially outwardly of the central hole or opening thereof capable of the reception of a circumferential axial 10. blade or projection therein as used in certain prior automatic dismounting roll mechanisms. The result is that rolls of toweling constructed in this manner will then be perfectly usable in dispensers adapted for satisfying the unique principles of the present 15. invention, yet at the same time, usable in the prior constructions of dispensers for providing the old form of roll automatic dismounting in such dispensers.
Other objects and advantages~of the invention will be apparent from the following speclfication 20. and the accompanying drawings which are for the purpose~
of illustration only.

20. Referring to FIGS.,l and 2 of the drawings,~
a somewhat standard roll of hollow core wound, strip ~ :
toweling is generally indicated at 10 incorporating a ~ :
preferred first embodiment of the automatic dismount~
ing roll principles of the present invention. As 25, in standard rolls of toweling, hollow, cylindrlcal , ~
. . .
_9_ ~ 7~7 core 12 having an axial, cen-tral opening or hole 14 may be formed of relatively stiff or rigid cardboard or other ma-terial and has a single-ply or multi-ply, continuous strip of toweling 16 wound circumferentially :~
5. thereabout to provide the roll 10. The central longitudinal ':
axis of the core 12 thereby forms the central or main longitudinal axis of the roll'10 and the combination of the ends of the core with the wound strip of towel- :
ing 16 form radially extending, opposite roll end 10. ' surfaces 18 for the roll 10.
More particularly according to the principles - ' of the present invention, one of the roll end surfaces 18 of the roll 10 is formed with a pair of preferably ~ :
'~ substantially identical, diametrically opposite! axial ~ :
15. pin holes or openings 20. The pin holes 20 are equal~
: ly radially spaced from the main longitudinal axis . ~ ~ -of the roll 10 and are located radially outwardly~of any core so as to be radially outwardly'of the core 12.' Thus, in the preferred embodiment shown,'~he .~ :
-?. pin holes 20 are cylindrical, axial holes having.
; radially inner extremities spaced radially outwardly ~: of the core 12 within the wound strip of towelling 16, the radially inner extremities of the pin holes 20 thereby being'likewise equally radially spaced from 25. the main longitudinal axis of the roll 10. The other :;
' --10--.
: :. 7 ' ' ' : , , , roll end surface 18 of this first embodimen-t roll 10 does not require any modification from a standard roll.
In formation of'this first embodiment roll of toweling 10, the core 12 is first wound with the S. strip of towellng 16 in usual well known manner to essentially form, at this stage, a standard roll of toweling.~ The pin holes 20 are then formed in the.
~individual rolls of towellng 10, that ls, ln the.wound .
strip of toweling 16 thereof, by drilling or other well ' lO. known cutting operations and precisely located as ' described.. For instance, the pin holes 20 may be . precisely formed in the roll lO on a high speed modern ~ ' :
'production basis using machines with usual precision . . . . .
~ .~igs or the like so as to reduce production time and '~ lS. expense to a minimum for this relatively simple, : : although precise, operation.
This first embodiment roll of toweling lO .
- is, therefore, adapted for use in a standard roll - . - ~' ~ ~ towel dispenser (not shown) only modified at first : 20. and second roll end holders generally indicated at 22 and Z4, respectively, otherwise the dispenser may , '. ~ be'of standard automatic dismounting roll type. :
As shown in FIG. 2 in a preferred modified form, the - first roll end holder 22 is rotatably secured an ~' 25. a dispenser mounting member 26 and the second roll . . ' ' ,~ , .....
7~7 : ~
end holder 24 ls rotatably secured on a dispenser mounting member 28, the two roll end holders, of course, being rotatably axially aligned in roll dispensing position. One or the other of the first and second 5. xoll end hoIders 22 or 24 with its particular mounting member 26 or 28 .is preferably positione.d in the dis- .
p nser selectively mova~le hingedly or otherwise : .
generally axially toward and away from its particular roll mounting position to permit the mounting of 10. ~he rolls of toweling 10 in the dispenser. . -~
~ The first roll end holder 22 includes . :
. .
: diametrically oppositej axial cylindrical pins 30 : -~
precisely located and sized for reception in the pin holes 20 of the roll of toweling 10 to securely re~
15. tain the roll rotatable about its maîn longitudinal ~ ~
axis. Equally spaced axially from its axial. : ~.
extremity, each o~ the pins 30 has a xadial abut-~
ment surface 3Z formed on the first roll end holder 22 extending tangentially adjacent the pln radially 20. inner extremities and circum~erentially around the pins radially outwardly thereof. These radial ;
abutment surfaces 32, thereby, de~ine a recess 34 in the first roll end holder 22 be~inning at ~he ~ :
- radially innex extremities o~ the pins 30 and extend-25. ing radially between the pins. The second roll end . , ' ' . ................... ~ ... . .
.
7~7 holder 24 includes radial, annular abutment surfaces 36 surrounding an axial, cylindrical, central core en-gagement member 38 sized for reception in the core opening 14 ancl thereby having radial extremities 5. spaced inwardly ~rom the radially inner extremities of the first holder pins 30 and the roll pin holes 20.
The first embodiment roll of toweling 10 may, therefore, be rotatably mounted by the first and second roll end holders 22 and 24 with the first - ' ::
lO. holder pins 30 received in the pin holes 20 at the one roll end surface 18 and the second holder engage- .
ment member 38 received in the opening 14 of the core 12 at the other roll end surface 18. As so positioned, . .
the ahutment.surfaces 32 and 36 of the first and - 15. second roll end holders 22 and 24 axially abut the roll end surfaces 18 of the roll lO so that these com~
bined ele~ents securely retain the roll of toweling ~ .
for rotating dispensing of the strip of toweling 16- :
. therefrom. Furthermore, upon the strip of toweling - 20. 16 being unrolled from the roll lO during dispensing completely uncovering the first holder pins 30 so as to substantially eliminate the pin holes 20 and reach the pin hole radially inner extremities, holding of that end of the roll lO is eliminated so that the 25. roll will endwise pivot about the second roll end ,..,~.
7~
holder 24 pivoting through the clearance provided by the recess 34 of the first roll end holder 22 and ultimately completely disengage free of the first and second roll end holders to complete the automatic 5. dismounting operation. .
Referring to FIG. 3, the preferred second embodiment of the automatic dismounting roll of the present invention is essentially the same as the first em~odiment form above described with the 10~ addition of one element of structure. The roll of .
toweling generally indicated at 40 is again a con~
tinuously wound strip of toweling 42 wound about a , central core 44 having the central opening or hole .
46. Radial roll en~ surfaces 48 are thereby formed lS. and diametrically opposite, axial pin holes 50 are similarly formed in the one roll end surace pre-cisely located in the roll 40 and relative to the core 44 as before. ~ ~ -The other roll end sur-face 48 of this 20. second embodiment form, however, includes the addition , of an annular, circumferentially extending groove 52 formed axially therein spaced radially outwardly of the core 44. A second roll end holder generally indicated at 54 includes a same cylindrical engage-25. ment member 56, similar radial abutment surfaces 58, : ~ . , , . , ~ . , a7~L7 but the addition of a circumEeren-tial projection 60 located radially at and received axially in the roll annular groove 52. Thus, the roll of toweling 40 may be firmly moun-ted between the same first roll end 5. holdex 22 and~the modified second roll end holder 54 wi-th the first holder pins 30 in the roll pin holes 50 at the one roll end surace 48 and the cylindrical engagement member 56 in the core central opening 46, the second holder circumferential projection 60 ~ .
10. inciaentally being receive.d in the rol,l groove 52 at the other roll end surface 48. , - -~ 'The combination of the roll annular,groove S2 and the second holder circumferential projection 6b is from a portion of a prior automatic dismounting '. ': .
15. rol'l structure and is ineffective as to automatic . ~ .
.roll dismounting according to -the present invention.
.
In other words, with.the roll 40 retained at the one roll end surface 48 by the first holder pins 30 in the roll pln holes 50 and at the other roll end sur~ace 20. 48 by the second holder engagement member 56 in the core opening 46 t roll dismounting will take place in .
the exact same manner as described above relative to the ~irst embodiment, the second holder engagement . member 56 eliminating any possible action as to roll 25. dismounting by the combined roll annular groove 52 7~:~7 and second holder circumferential projection 60. The addition of this roll circumferential groove 52 and the second holder circumferential projection, however, adapts the roll 40 for reception in dispensers of 5. other appropriate forms and automatic dismounting in such other dispensers, thereby adding versatility to :-the roll of toweling 40.
In the third embodiment form încorporating the principles of the present invention as shown in. -.
10. FIG~ 4, a roll of toweling generally indicated at 62 is a solid wound roll of toweling from a strip of :
: toweling 64 so that there is no core, but still radial roll end surfaces 66. However, -the roll 64 is still again formed with diametrically opposite pin holes 68 15. equally radially spaced from the central or main longitudinal axis of the roll 62 so as to be formed and located in precisely the same positions as in the .
first and second embodiments and effectively operable in the same manner with the pins 30 o~ the first roll 20. end holder 22. At the other roll end surface 66, the roll 62 is formed with a central axial opening or . : , hole 70 coaxial with the roll main longitudinal axis and in the preferred form, semi-spherical.
A second roll end holder generally indicated 25. at 72 of this third embodiment form includes similar .
' ., , ~47~l7 radial abutment surfaces 74 and a central, axial engage-ment member 76 semi-spherical in shape correspondin~
to the roll semi-spherical cen-tral opening 70. In view of the fact that the roll central opening 70 5. and the corresponding second holder engagemen-t member 76 are of this semi-spherical shape, the radially ~ .
outer extremities thereof are not of importance since that end of the roll 62 will be retained substantially until the strip of toweling 64 is at the xoll main , 10. longitudinal axis, in other woxds, the automatic ~
dismounting release of the roll 62 will still be .
solely determined by the rolI pin holes 68 and ~he .
:~ . first holder pins 30 at the first roll end surface . . - ~ .
66 as before. However, if the roll central opening ~ ~ .
-~ : 15. 70 and the second holder engagement member 76 are .
formed corresponding cylindrical shapes J the outer .
~ extremities thereof would necessarily be~not greater .
in radial dimension than the radially innex extremities of the roll pin holes 68 and the first 20. holder pins 30, and preferably spaced radially in~
wardly therefrom, in order that the automatic roll ~ :
dismounting will remain totally controlled by the roll pin holes and first holder pins at that roll end surface 66.
25. In any event, with the construction des-- ' ' . , ~47~L7 cribed, this third embodimen-t roll of toweliny 62 will be securely retained between the first and second roll end holders 22 and 7~ until a suf~icient amount of the strip of toweling 64 is unrolled therefrom to 5. reach the radially inner extremities of the roll pin holes 68. At this time, the first holder pins 30 will no longer be capable of supporting that end of the roll 62 permitting the same to drop by gravity through the clearance afforded by the first holder 10. recess 34 and endwise pivoting about the second roll end holder 72. ~s in the other embodiments, the - roll 62 will ultimately become disengaged from both of the first and second roll end holders 2Z and 72 dropping downwardly and completing the automatic ~ -- - -- , . .
15. dismounting operation. -According to the principles of the present invention, therefore, in all three embodi-ments of the automatic dismounting rolls 10, 40 or -62, the rolls are very simply, but yet very securely 20. retained by the cooperation of the roll pin holes 20, 50 or 68 and the roll central openings 14, 46 or 70 . ........ .. ..
during the dispensing operation. Despite the simplicity and highly secure support, however, when the radially inner extremities of the roll pin holes 25. Z0, 50 or 68 are reached, the particular roll is : . ~ , ............................... , .................. -, ... .
1~476~7 efficiently automa-tically dismounted, all as herein~
before described. Furthermore, by the addition of certain other roll structure forming a part of the automatic dismounting structure of prior roll con-5. structions, it is possible to add versatility to the principles of the present invention so that the roll or rolls formed according to the present in-vention may be interchangeably used in the appropriate : priox dispensers. Finally, with only very minor :
10. chan~es, the principles of the present invention are .: readily adapted to solid, strip wound rolls of towel-: ing 62 which automatically dismount in the same .
efficient manner. .

In other words, the roll end holder and roll . are cooperably ~ormed such that the roll will be supported by the roll end holder properly rotatable . ..
or disperlsing until a given number of layers of the - `
10. -toweling have been rotatably wound therefrom, at ~.
which time, a portion of the roll end holder is auto- . -- :.
~ matically exposed to automatically remove the roll .
support of that particular roll end holder and the ~roll thereby is automatically released through .-- . 15. . gravity to pivot endwise about the other roll end holder ultimately falling downwardly to come to rest ~ ~`
within the dispenser used roll recess as hereinbefore : described. It is the rolls of toweling used by ~ ~
this general form of automatic roll dismounting dis- ~ .
20. pensers to which the improvements of the present : :
invention are directed.
Obiects and Summary of the Invention It is, therefore, an object~of this invention ~:
25. to provide an automatic dismounting roll for roll towel , ~, . .
~7~:~7 dispensers which is adap-ted for highly secure rotatable suppor-t in a dispe~ser during the normal dispensing operations of a strip of toweling therefrom, yet is :~
also adapted for efficient and positive automatic S. dismounting after a predicted amount of the strip of toweling has been thusly dispensed. According to the preferred embodiment principles.of the present :
invention, one of the roll end surfaces has diametrically ..
opposite pin holes formed axially therein equally 10. radially spaced from the main longitudinal axis of-the roll and radially outwardly o~ any roll core, . ~-and the other end surface of the roll merely re~uires .
structure adapted for central roll support. - For instance, if the toweling roll is of solid wound strip,~
lS. the central support for the other roll end surface - may merely be a central axial hole or opening and if . .
the roll includes a central core, the central support.
at *he other r~oll end surface may be in the core end . such as the opening of a hollow core. In any case, ~.
: 20. wi~h ~he roll dispenser supported by appropriate pins in the pin holes and a central support in the central support hole or opening, unwinding of the strip of toweling during dispensing to the pin hole rad}ally inner extremities will.release the one end of the -~
25. roll to pivot endwise about the other end central , " ' ' ' ' ' ' .
~L~47~17 ~ ~
support, there~y efficiently dismounting -the same.
It is another object of this invention to provide an automatic dismounting roll for roll towel dispensers o the foregoing general structure and 5. advantages which, due to the extreme simplicity of the roll support and dismounting concept, may ~e manufactured and supplied for a minimum of additional cost over rolls of toweling not including the auto-matic dismounting feature and at a manufacturing lO. cost less than prior automatic dismounting rolls of - toweling. . With a core wound roll of toweling, the only required added structure over the usual standard roll of toweling is the pin holes at the one roll en surface, and if the roll is solid wound without a ~
15. .core, only the central opening at the other roll end surface need be added to the pi~ openings. Thus, the cost of manufacture of the unique automatic dis~
mounting roll of the present invention over standard : ~ .
.
rolls of toweling is quite nominal despite the auto- :
,: ~
~: 20. matic dismounting advantages added thereto.
. It is still a further object of this in~ . ~
vention to provide an automatic dismounting roll for ~ ~ :
roll towel dispensers satisfying the foregoing objects, while still being perfectly adaptable to the inclusion ~5. in the structure of an additional element or elements ,:
, . . . .
:
7~7 supplying versatility for alternate use of the same roll of toweling with certain prior roll towel dispensers having a different form,of automatic dismounting roll.
Using the exact above discussed toweling roll structure 5. to supply a roll incorporating the unique features of the present invention, a circumferential groove may be formed in the other roll end surface spaced radially outwardly of the central hole or opening thereof capable of the reception of a circumferential axial 10. blade or projection therein as used in certain prior automatic dismounting roll mechanisms. The result is that rolls of toweling constructed in this manner will then be perfectly usable in dispensers adapted for satisfying the unique principles of the present 15. invention, yet at the same time, usable in the prior constructions of dispensers for providing the old form of roll automatic dismounting in such dispensers.
Other objects and advantages~of the invention will be apparent from the following speclfication 20. and the accompanying drawings which are for the purpose~
of illustration only.

20. Referring to FIGS.,l and 2 of the drawings,~
a somewhat standard roll of hollow core wound, strip ~ :
toweling is generally indicated at 10 incorporating a ~ :
preferred first embodiment of the automatic dismount~
ing roll principles of the present invention. As 25, in standard rolls of toweling, hollow, cylindrlcal , ~
. . .
_9_ ~ 7~7 core 12 having an axial, cen-tral opening or hole 14 may be formed of relatively stiff or rigid cardboard or other ma-terial and has a single-ply or multi-ply, continuous strip of toweling 16 wound circumferentially :~
5. thereabout to provide the roll 10. The central longitudinal ':
axis of the core 12 thereby forms the central or main longitudinal axis of the roll'10 and the combination of the ends of the core with the wound strip of towel- :
ing 16 form radially extending, opposite roll end 10. ' surfaces 18 for the roll 10.
More particularly according to the principles - ' of the present invention, one of the roll end surfaces 18 of the roll 10 is formed with a pair of preferably ~ :
'~ substantially identical, diametrically opposite! axial ~ :
15. pin holes or openings 20. The pin holes 20 are equal~
: ly radially spaced from the main longitudinal axis . ~ ~ -of the roll 10 and are located radially outwardly~of any core so as to be radially outwardly'of the core 12.' Thus, in the preferred embodiment shown,'~he .~ :
-?. pin holes 20 are cylindrical, axial holes having.
; radially inner extremities spaced radially outwardly ~: of the core 12 within the wound strip of towelling 16, the radially inner extremities of the pin holes 20 thereby being'likewise equally radially spaced from 25. the main longitudinal axis of the roll 10. The other :;
' --10--.
: :. 7 ' ' ' : , , , roll end surface 18 of this first embodimen-t roll 10 does not require any modification from a standard roll.
In formation of'this first embodiment roll of toweling 10, the core 12 is first wound with the S. strip of towellng 16 in usual well known manner to essentially form, at this stage, a standard roll of toweling.~ The pin holes 20 are then formed in the.
~individual rolls of towellng 10, that ls, ln the.wound .
strip of toweling 16 thereof, by drilling or other well ' lO. known cutting operations and precisely located as ' described.. For instance, the pin holes 20 may be . precisely formed in the roll lO on a high speed modern ~ ' :
'production basis using machines with usual precision . . . . .
~ .~igs or the like so as to reduce production time and '~ lS. expense to a minimum for this relatively simple, : : although precise, operation.
This first embodiment roll of toweling lO .
- is, therefore, adapted for use in a standard roll - . - ~' ~ ~ towel dispenser (not shown) only modified at first : 20. and second roll end holders generally indicated at 22 and Z4, respectively, otherwise the dispenser may , '. ~ be'of standard automatic dismounting roll type. :
As shown in FIG. 2 in a preferred modified form, the - first roll end holder 22 is rotatably secured an ~' 25. a dispenser mounting member 26 and the second roll . . ' ' ,~ , .....
7~7 : ~
end holder 24 ls rotatably secured on a dispenser mounting member 28, the two roll end holders, of course, being rotatably axially aligned in roll dispensing position. One or the other of the first and second 5. xoll end hoIders 22 or 24 with its particular mounting member 26 or 28 .is preferably positione.d in the dis- .
p nser selectively mova~le hingedly or otherwise : .
generally axially toward and away from its particular roll mounting position to permit the mounting of 10. ~he rolls of toweling 10 in the dispenser. . -~
~ The first roll end holder 22 includes . :
. .
: diametrically oppositej axial cylindrical pins 30 : -~
precisely located and sized for reception in the pin holes 20 of the roll of toweling 10 to securely re~
15. tain the roll rotatable about its maîn longitudinal ~ ~
axis. Equally spaced axially from its axial. : ~.
extremity, each o~ the pins 30 has a xadial abut-~
ment surface 3Z formed on the first roll end holder 22 extending tangentially adjacent the pln radially 20. inner extremities and circum~erentially around the pins radially outwardly thereof. These radial ;
abutment surfaces 32, thereby, de~ine a recess 34 in the first roll end holder 22 be~inning at ~he ~ :
- radially innex extremities o~ the pins 30 and extend-25. ing radially between the pins. The second roll end . , ' ' . ................... ~ ... . .
.
7~7 holder 24 includes radial, annular abutment surfaces 36 surrounding an axial, cylindrical, central core en-gagement member 38 sized for reception in the core opening 14 ancl thereby having radial extremities 5. spaced inwardly ~rom the radially inner extremities of the first holder pins 30 and the roll pin holes 20.
The first embodiment roll of toweling 10 may, therefore, be rotatably mounted by the first and second roll end holders 22 and 24 with the first - ' ::
lO. holder pins 30 received in the pin holes 20 at the one roll end surface 18 and the second holder engage- .
ment member 38 received in the opening 14 of the core 12 at the other roll end surface 18. As so positioned, . .
the ahutment.surfaces 32 and 36 of the first and - 15. second roll end holders 22 and 24 axially abut the roll end surfaces 18 of the roll lO so that these com~
bined ele~ents securely retain the roll of toweling ~ .
for rotating dispensing of the strip of toweling 16- :
. therefrom. Furthermore, upon the strip of toweling - 20. 16 being unrolled from the roll lO during dispensing completely uncovering the first holder pins 30 so as to substantially eliminate the pin holes 20 and reach the pin hole radially inner extremities, holding of that end of the roll lO is eliminated so that the 25. roll will endwise pivot about the second roll end ,..,~.
7~
holder 24 pivoting through the clearance provided by the recess 34 of the first roll end holder 22 and ultimately completely disengage free of the first and second roll end holders to complete the automatic 5. dismounting operation. .
Referring to FIG. 3, the preferred second embodiment of the automatic dismounting roll of the present invention is essentially the same as the first em~odiment form above described with the 10~ addition of one element of structure. The roll of .
toweling generally indicated at 40 is again a con~
tinuously wound strip of toweling 42 wound about a , central core 44 having the central opening or hole .
46. Radial roll en~ surfaces 48 are thereby formed lS. and diametrically opposite, axial pin holes 50 are similarly formed in the one roll end surace pre-cisely located in the roll 40 and relative to the core 44 as before. ~ ~ -The other roll end sur-face 48 of this 20. second embodiment form, however, includes the addition , of an annular, circumferentially extending groove 52 formed axially therein spaced radially outwardly of the core 44. A second roll end holder generally indicated at 54 includes a same cylindrical engage-25. ment member 56, similar radial abutment surfaces 58, : ~ . , , . , ~ . , a7~L7 but the addition of a circumEeren-tial projection 60 located radially at and received axially in the roll annular groove 52. Thus, the roll of toweling 40 may be firmly moun-ted between the same first roll end 5. holdex 22 and~the modified second roll end holder 54 wi-th the first holder pins 30 in the roll pin holes 50 at the one roll end surace 48 and the cylindrical engagement member 56 in the core central opening 46, the second holder circumferential projection 60 ~ .
10. inciaentally being receive.d in the rol,l groove 52 at the other roll end surface 48. , - -~ 'The combination of the roll annular,groove S2 and the second holder circumferential projection 6b is from a portion of a prior automatic dismounting '. ': .
15. rol'l structure and is ineffective as to automatic . ~ .
.roll dismounting according to -the present invention.
.
In other words, with.the roll 40 retained at the one roll end surface 48 by the first holder pins 30 in the roll pln holes 50 and at the other roll end sur~ace 20. 48 by the second holder engagement member 56 in the core opening 46 t roll dismounting will take place in .
the exact same manner as described above relative to the ~irst embodiment, the second holder engagement . member 56 eliminating any possible action as to roll 25. dismounting by the combined roll annular groove 52 7~:~7 and second holder circumferential projection 60. The addition of this roll circumferential groove 52 and the second holder circumferential projection, however, adapts the roll 40 for reception in dispensers of 5. other appropriate forms and automatic dismounting in such other dispensers, thereby adding versatility to :-the roll of toweling 40.
In the third embodiment form încorporating the principles of the present invention as shown in. -.
10. FIG~ 4, a roll of toweling generally indicated at 62 is a solid wound roll of toweling from a strip of :
: toweling 64 so that there is no core, but still radial roll end surfaces 66. However, -the roll 64 is still again formed with diametrically opposite pin holes 68 15. equally radially spaced from the central or main longitudinal axis of the roll 62 so as to be formed and located in precisely the same positions as in the .
first and second embodiments and effectively operable in the same manner with the pins 30 o~ the first roll 20. end holder 22. At the other roll end surface 66, the roll 62 is formed with a central axial opening or . : , hole 70 coaxial with the roll main longitudinal axis and in the preferred form, semi-spherical.
A second roll end holder generally indicated 25. at 72 of this third embodiment form includes similar .
' ., , ~47~l7 radial abutment surfaces 74 and a central, axial engage-ment member 76 semi-spherical in shape correspondin~
to the roll semi-spherical cen-tral opening 70. In view of the fact that the roll central opening 70 5. and the corresponding second holder engagemen-t member 76 are of this semi-spherical shape, the radially ~ .
outer extremities thereof are not of importance since that end of the roll 62 will be retained substantially until the strip of toweling 64 is at the xoll main , 10. longitudinal axis, in other woxds, the automatic ~
dismounting release of the roll 62 will still be .
solely determined by the rolI pin holes 68 and ~he .
:~ . first holder pins 30 at the first roll end surface . . - ~ .
66 as before. However, if the roll central opening ~ ~ .
-~ : 15. 70 and the second holder engagement member 76 are .
formed corresponding cylindrical shapes J the outer .
~ extremities thereof would necessarily be~not greater .
in radial dimension than the radially innex extremities of the roll pin holes 68 and the first 20. holder pins 30, and preferably spaced radially in~
wardly therefrom, in order that the automatic roll ~ :
dismounting will remain totally controlled by the roll pin holes and first holder pins at that roll end surface 66.
25. In any event, with the construction des-- ' ' . , ~47~L7 cribed, this third embodimen-t roll of toweliny 62 will be securely retained between the first and second roll end holders 22 and 7~ until a suf~icient amount of the strip of toweling 64 is unrolled therefrom to 5. reach the radially inner extremities of the roll pin holes 68. At this time, the first holder pins 30 will no longer be capable of supporting that end of the roll 62 permitting the same to drop by gravity through the clearance afforded by the first holder 10. recess 34 and endwise pivoting about the second roll end holder 72. ~s in the other embodiments, the - roll 62 will ultimately become disengaged from both of the first and second roll end holders 2Z and 72 dropping downwardly and completing the automatic ~ -- - -- , . .
15. dismounting operation. -According to the principles of the present invention, therefore, in all three embodi-ments of the automatic dismounting rolls 10, 40 or -62, the rolls are very simply, but yet very securely 20. retained by the cooperation of the roll pin holes 20, 50 or 68 and the roll central openings 14, 46 or 70 . ........ .. ..
during the dispensing operation. Despite the simplicity and highly secure support, however, when the radially inner extremities of the roll pin holes 25. Z0, 50 or 68 are reached, the particular roll is : . ~ , ............................... , .................. -, ... .
1~476~7 efficiently automa-tically dismounted, all as herein~
before described. Furthermore, by the addition of certain other roll structure forming a part of the automatic dismounting structure of prior roll con-5. structions, it is possible to add versatility to the principles of the present invention so that the roll or rolls formed according to the present in-vention may be interchangeably used in the appropriate : priox dispensers. Finally, with only very minor :
10. chan~es, the principles of the present invention are .: readily adapted to solid, strip wound rolls of towel-: ing 62 which automatically dismount in the same .
efficient manner. .
